SPECIFICATION forming part of Letters Patent No. 728,063, dated May12,1903. Application filed September 8, 1902. Serial llo. 122,543. onmodel.)

To all whom it may concern:

Beit known that], RICHARD WILSON, a citizen of the United States, and aresident of the city of New York, borough of Manhattan, in

the county and State of New York, have invented a new and ImprovedTransparent Mir- I ror, of which the following is a full clear, and

exact description.

The object of the invention is to provide a new and improved transparentmirror arranged to reflect images and to allow of see"- ing through itaccording to the amount of light in the background-that is, when thebackground is darkened the transparent mirror reflectsimages in front ofit, and when the background is lighted the mirror becomes transparent-JThe invention consists of novel features and parts and combinations ofthe same, as will he more fully described hereinafter and then pointedout in the claims.

Reference is to be had to'the accompanyingi drawing, forming a part ofthis specification, iu which the figure is a transverse section of theimprovement as arranged in a showwindow.

The transparent .mi-rror consists, essentially, of a transparent ortranslucent sheet -or plate A of glass or similar transparent ortranslucent materialtand a transparentand reflecting coating B on theback of the sheet or plate .A, the coating being capable'i of refleetingthe image of an objectiu front of the device on providing the latterwith a dark background or allowing a person to see through the plate andcoating ona lighted background.

It is understood that the coating B is capabio of rendering the platereflective,- and at ing in case an illuminated background is provided.The coating B consists of a silvering such as is usually employed formaking ordinary mirrors, and this silv'ering is applied to the sheet orplate and then a second subsequent coating is applied to the firstcoating, and this second coating consists of amyl acetate, ten

ounces; dissolved guncotton, one hundred grams; fusel-oil, five ounces.

The ingredients of the second coating are the light Wheuthe device isarranged in front of a dark background, then the coating has areflecting property, thus forming of the plate and coating a mirror. t

The device may be used for various purposes-such as illusive stageeliects, in'showwindows, as advertising mediums, and in showcases, as,for, instance, shown in the drawing -it being understood that inshowwindows the front plate is formed of a transparent mirror, asdescribed, and the sides and back of the show-window-are arranged to helight-tight, and in the show-window is arranged an illuminating deviceto illuminate the background, and thereby allow a person standing infront of the show-windowto-view the goods through the transparent mirrorin a the usual manner; but when the'illumina'ting device is extinguishedand the show-wimdow background becomes dark then the trans-.

parent mirror acts as a mirror only and re fleets the image of theperson in front of the show-window without allowing the person to seethe goods displayed in the show-window.

Having thus described my invention, I claim as new and desire to secureby Letters Patentv I v v 1. As a new article of manufacture, a mirrorhaving the ordinary silvered surface, and a' coating over saidsilvering, r endering the same transparent without "destroying itsreflective properties, as specified and for the purpose set'forth;

As a new article of manufacturga trans- IOO 2 sashes parent mirrorconsisting of a transparent or translucent plate, and a coating on theback of the plate, capable of rendering the plate reflective, thecoating being transparent or translucent and consisting of a silvei'ingmaterial, amyl acetate, guncotton and fusel-oil, as set forth.

3. The herein -described composition for rendering the mirror-silveringmaterial transparent and. reflective, consisting of smyl acein tate,guncotton and. fn sel-oii as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
